prevent a spring fioin workin g into the wrong section of the ring,making it unnecessary to indent the iing to position the springs.

Iii the usual size lof mattress forty such units are employed, as shown,lbut this, of course, can be varied to suit the taste, theallimportant'point being the unitary construction by which each biscuitis ena-bled to oper'- ate independently of allof the rest, therebypreventing the stretching and sagging which is common in mostmattresses. i

lVhen as many units of the device have been assembled as there are to bebiscuits in the completed mattress, the assembled device is covered withlight cloth 19 and oneV or more layers ofthe desired filler 20, afterwhich it is placed in the ticking 21 'and tufted and roll edgedas is thecommon practice. l

In some cases it may be found desirable to employ more'filler onone'side of the mattress than on the other lor` to increase the number,of turns of the spring coils 13 on the oct-agonal ring, or to employmore than the eight spring pairs showii in each biscuit.

` These and other minor changes, suclias the style of coupling ring 18,the shape of the ring 10, etc. may be varied without departing from thespirit of our invention.

A mattress constructed as above described is free to be rolled in eitherrdirection or bent in any form without danger of injuring the mattress.l Y

Owing to the fact that initial tension is i supplied 'to the springs 12it follows that any slight weakening of a spring, due to constant use,will still leave suiticient strength to bring the cover 117 and ofcourse the biscuit 22, up

to the proper position. Since any of the biscuits can be depressedindependently of any ofthe other biscuits and will returiito it-soriginal position it follows thatit is a physical impossibility forthemattress to stretch or sag. y

The size of the coil 13 is sufficient to permit its lateral movement onthe vring 10. y Inlits normal position it limits the separation of theanchors 11 and in its out-ward position `it of each spring, a secondyanchor secured to Expressing the saine matter somewhat,dilferently the)unc--V tion point or corners of the ring serve to theother or free endof' each spring, whereby as the 'bowed'V springs open `or expand theanchors are moved apart, and a single means positioned outside ofthespace` between the two anchors for limiting the expansion ofthesprings, while offering'no resistance to the approach of the twoanchors as the spring liex under load, said means being substantiallynon-extensible in length.
